Handle access control on var declarations instead of via [[access]]
decorations. This change does the minimal work to migrate the WGSL
parser over to the new syntax. Additional changes will be needed
to correctly generate defaulted access qualifiers, as well as
validating access usage.
The [[access]] decorations are still supported by the WGSL parser,
with new deprecated warnings, but not for aliases. Example:
var x : [[access(x)]] alias_to_struct;
Making this work is far more effort than I want to dedicate to backwards
compatibility, and I do not beleive any real-world usage will be doing
this.
Still TODO:
* Adding access control as the optional, third parameter to ptr<>.
* Calculating default accesses for the various storage types.
* Validating usage of variables against the different accesses.

We're about to add Yet Another optional parameter - access control.
For style, we probably want this field before the decorations, however
that means adding more default values for all the cases where we don't
need to specify the access control.
Instead use some template magic to allow extra parameters to be
specified in any order, and entirely optional, with sensible defaults.
This keeps things readable and without huge code refactorings.

Sometimes a value can come from a block which does not appear
in the structured block order. That block will never execute,
so we can safely use the null value instead.

Previous logic relied on the fact that for most operations, for a given

multiplication. This is no longer true in the spec, so making this test

take the cartesian product of all possible (type * type * op), and
skipping any triplet not found in the all_valid_cases table.

The Resolver processes these nodes to produce a uint32_t for the
default value on each dimension, and captures a reference to the
module-scope constant if it is overridable (which will soon be used by
the inspector and backends).
The WGSL parser now uses `primary_expression` to parse arguments to

This reverts commit 594075a2f0.
Reason for revert: This is not a complete solution. It does not cover assignment of variables of the same struct type, but of different access types. For example:
```
[[block]] struct S{ i : 32; };
var<storage> gr : [[access(read)]] S;
var<storage> gw : [[access(write)]] S;
fn f() {
var a : S;
a = gr;
gw = a;
}
```
With my CL, we currently generate invalid assignments because the new types of 'S' for 'gr' and 'gw' are now all different types. We would need to generate functions to assign between them.
In the end, we will drop this strategy, and instead, Dawn will be modified to not rely on names.
Original change's description:
> Add DuplicateStorageStruct transform
>
> This transform is currently required by Dawn for it's GLSL backend so
> that SPIRV-Cross does not end up renaming the structures internally,
> which it does to fix aliasing problems. We can remove this transform
> if/once Dawn using binding numbers rather than names for uniform/storage
> buffer data.

This transform is currently required by Dawn for it's GLSL backend so
that SPIRV-Cross does not end up renaming the structures internally,
which it does to fix aliasing problems. We can remove this transform
if/once Dawn using binding numbers rather than names for uniform/storage
buffer data.

This change implements pointers and references as described by the WGSL
specification change in https://github.com/gpuweb/gpuweb/pull/1569.
reader/spirv:
* Now emits address-of `&expr` and indirection `*expr` operators as
needed.
* As an identifier may now resolve to a pointer or reference type
depending on whether the declaration is a `var`, `let` or
parameter, `Function::identifier_values_` has been changed from
an ID set to an ID -> Type* map.
resolver:
* Now correctly resolves all expressions to either a value type,
reference type or pointer type.
* Validates pointer / reference rules on assignment, `var` and `let`
construction, and usage.
* Handles the address-of and indirection operators.
* No longer does any implicit loads of pointer types.
* Storage class validation is still TODO (crbug.com/tint/809)
writer/spirv:
* Correctly handles variables and expressions of pointer and
reference types, emitting OpLoads where necessary.
test:
* Lots of new test cases

Add a new parameter to BindingRemapper::Remappings that allows resulting binding points to collide.
When enabled, the output of the transform contains two or more module-scoped variables with the same binding point, used by the same entry point, then these variables will be decorated with an internal decoration to disable validation for the collision.
This is to work around collisions generated for the HLSL backend where the variables actually exist in different register classes, which is permitted by D3D12.
The transform will only generate these decorations if it needs to.

WGSL now supports type inferencing with `let` declarations, so `var->type()` may return nullptr.
Calling a method (`Is<T>()`) on a nullptr object is UB. Instead used the free-function form which can handle nullptr objects.

- Add optional second argument test/test-all.sh to specify a directory

- BUILD.gn: Add dependency from //test:tint_unittests_main to

The spirv parser now creates ast types along with sem types via
typ::Type. All sem::Type* were replaced with typ::Type, and its `ast`
member is used over the `sem` member to make it easier to migrate to
ast-only.
The parser was written to take advantage of the fact that types were
resolved to semantic types during parsing. For instance, a mapping of
spirv typeid to sem::Type* was used throughout (`id_to_type_`) to
resolve types once, and to support type aliasing. Since the goal is to
only create AST types, and to resolve only in the Resolver, I made many
changes to remove this dependency on semantic types. For instance, we
now always call ConvertType(typeid) instead of looking up via
id_to_type. Similarly, the `signed_type_for_` and `unsigned_type_for_`
maps were replaced with `UnsignedTypeFor` and `SignedTypeFor` functions.

Instead of printf-ing and returning an empty string.
When there's a lot of other test output, it can be really hard to actually spot the error message.
With the error being returned, this will likely appear in a EXPECT_EQ() style error message.

This takes precedence over semantic types.
WGSL should be printed as faithfully as possible to the parsed program.
The semantic nodes are more abstract than the AST - aliases are folded
away, decorations may be absorbed into the semantic types, etc.

Also:
* Added specialization of OperatorArrow for type::TypePairs that returns
the value by reference so that operator-> can chain properly.
* In a few places where we expect the type to implicitly cast to a
pointer for a bool expression, e.g. `if (type)` or `TINT_ASSERT(type)`,
I added access to the `.sem` member of the TypePair. I tried adding an
implicit cast to bool, but this results in ambiguity in gtest for

AST nodes must not be shared. Diamonds in the AST will cause all sorts
of exciting, non trivial bugs.
All AST nodes must be reached by the Resolver. There are two common
reasons why they may not be:
(a) They were constructed and not attached to the AST. Several
transforms scan the full list of constructed AST nodes to find nodes
of a given type. Having detached nodes will likely cause bugs in
these transforms. Detached nodes is also just a waste of memory.
(b) They are attached to the AST, but the resolver did not traverse
them. Having the resolver skip over parts of the AST will fail to
catch validation issues, and will leave semantic gaps, likely
breaking downstream logic.

This makes the .cc files match the header file name, which allows for
the text editor "header flip" feature to actually work. The reason these
files were named this way was because GN doesn't allow name conflicts in
the same source set, despite the files being in different directories.
This change splits the files into different source sets. To do so, we
use GN templates, which also reduces duplication in each target
definition.

The CloneContext will currently de-duplicate any pointers that are cloned multiple times, however this isn't ideal behavior for AST nodes.
AST nodes must be unique in the tree, so a non-transform clone of the AST from one program to another should only ever Clone() called once per node. Hitting the map for these is inefficent, worse still, there are cases in the transforms where we actually *want* to create N copies of the same source node. The current implementation makes this impossible.
This change introduces ShareableCloneable, a new base class that derives from Cloneable.
Repeated calls to CloneContext::Clone() for Cloneable pointer types will now produce a new, unique instance per call.
Repeated calls to CloneContext::Clone() for ShareableCloneable pointer types will de-duplicate as before.
type::Type objects are shared, want deduplication while cloning, so now derive from ShareableCloneable.
ast::Node continues to derive from Cloneable.

The canonical type was stopping at the first encountered type::AccessControl, which meant the alias in access<alias<i32>> was not being unwrapped.

Move transform::Transform::Output to transform::Output.
There's no need for this to be an nested class, it stutters, and it also
prevents Dawn from forward declaring it.
Add move assignment operator to DataMap.

Adds additional modes to the Renamer for renaming just HLSL or MSL
keywords. The sanitizers no longer rename reserved keywords
automatically, which isn't usually necessary anyway since Dawn renames
all symbols.
The tint executable automatically renames reserved keywords when
targeting HLSL and MSL. It now also has an option to rename
everything, which is useful for testing the renamer.

type::Array was the only type with special handling in that we'd resolve
all array types first in ResolverInternal, then proceed with resolving
the AST in order of declaration. This CL removes this special handling,
and instead, we now process Arrays as we process ast::Variables of
array type. This change also allows us to pass down a Source location
for validation messages when processing Arrays.
Updated some Builder tests that weren't creating a variable of the array
type they declared.

Don't end the EXPECT_THAT() with `<< ToString(p->builder(), fe.ast_body());`
This string is already emitted in the error, and calling ast_body() a second time triggers an assert as the builder is already finalized.

The MSL writer GTest harness (TestHelper) now provides a function to
invoke the XCode SDK Metal compiler for the MSL output of a given
tint::Program.
The tint_unittests binary now provides the `--validate-msl` and
`--xcrun-path` command-line flags to optionally enable MSL validation
and to configure its path.
The MSL validation logic itself is conditionally compiled based on the
TINT_BUILD_MSL_WRITER define. The TINT_BUILD_* flags were previously
not propagated to the GTest binary which this CL addresses by linking
the common/public tint configs when building the tint_unittests_main
target.
